The demand function for a certain item is
x=(p+2)9e−px=(p+2)9e−p
Use interval notation to indicate the range of prices corresponding to elastic, inelastic, and unitary
NOTE: When using interval notation in WeBWorK,
remember that:
You use 'I' for ∞∞ and '-I' for −∞−∞.
And use 'U' for the union symbol.
a) The range of prices for elastic is
b) The range of prices for inelastic is
a) The prices for unitary is
